2 DNA barcoding DNA based species identification
Once reference barcodes are established will always be able to identify that species Internationally agreed regions of DNA used: rbcL & matK for plants Open science >Cotoneaster_cambricus AGAGACTAAAGCAAGTGTTGGATTCAAAGCTGGTGTTAAAGATTATAAATTGACTTATTATACTCCTGACTATGAAACCAAAGATACTGATATTTTGGCAGCATTTCGAGTAACTCCTCAACCTGGAGTTCCACCTGAGGAAGCAGGGGCCGCGGTAGCTGCTGAATCTTCTACTGGTACATGGACAACTGTATGGACTGACGGTCTTACCAGTCTTGATCGTTACAAAGGTCGATGCTACCACATCGAGCCTGTTGCTGGAGAAGAAAGTCAATTTATTGCTTATGTAGCTTACCCCTTAGACCTTTTTGAAGAAGGTTCTGTTACTAACATGTTTACTTCCATTGTAGGTAATGTGTTTGGGTTCAAGGCCCTGCGCGCTCTACGTCTGGAGGATTTGCGAATCCCTACTGCTTATGTTAAAACTTTCCAGGGCCCGCCTCATGGTATCCAAGTTGAGAGAGATAAATTGAACAAGTATGGCCGCCCTCTATTGGGATGTACTATAAAACCAAAATTGGGGTTATCCGCTAAGAATTACGGTAGAGCAGTTTATGAATGTC

3 What pollen is it carrying?
What do they eat? What’s in this? What pollen is it carrying? Is this legal?

4 Barcode Wales: Cod Bar Cymru
DNA barcode the native flowering plants and conifers of Wales Develop applications that utilise this research platform

5 Sample collection 1143 native flowering plants and conifers
4272 individuals sampled, 3637 herbarium, 635 freshly collected All specimens verified by taxonomic expert Herbarium vouchers and full collection details for all samples

6 DNA barcoding protocol
DNA extraction: Qiagen kits, modified for herbarium material Amplification: rbcL 5 & matK 23 primer combinations Sanger sequencing Manual editing, multiple alignment Sequences uploaded onto BOLD & GenBank – publically available

8 Recoverability rbcL matK rbcL & matK No. of spp. sequenced (1143) 1117 (98%) 1031 (90%) 1025 (90%) No. of spp. with > 1 individual sequenced 1041 (91%) 814 (71%) 808 (71%) Mean no. of individuals per spp. 3 2 Mode of individuals per spp. Range of individuals per spp. 1 - 9 1 - 8 Total no. of individuals sequenced 3304 2419 2349 In total 5,723 barcode sequences obtained for the 1143 species

9 Effect of herbarium specimen age
Spearman Rank Correlation: rbcL rho = 0.993*** matK rho = 0.986***

10 Relative discrimination
808 species with multiple individuals sequenced for both rbcL & matK 69 99 75 100 68 98 74 99 56 96 57 95

11 rbcL & matK discrimination
Scale n Mean discrimination % (SD) 10x10 km 253 82 (3) 2x2 km 1116 93 (6) Species lists generated for each square, discrimination assessed by presence of a barcode gap

12 Roots, shoots and pollen
Root analysis Identification at single pollen grain resolution Identification of pollen products Gives a feeling “of Youthful Exuberance!”

13 Honey and drug discovery
Collect honey from throughout the UK. Test antibacterial properties of honey against MRSA and Clostridium difficile. DNA barcode honey using next generation DNA sequencing (454). Identify plant derived phytochemicals that increase antimicrobial activity.

14 MRSA – prelim results

16 DNA barcoding and phylogenetics
ML tree for rbcL, RAxML (GTR+CAT) 1000 bootstraps, on the CIPRES supercomputer cluster 56% of species form monophyletic groups 44% with bootstrap support >70%

17 DNA barcoding and phylogenetic ecology
ML tree for rbcL, threatened species traced using Mesquite

18 What’s next? Barcode UK Barcode Alien Phylogeny for the UK flora
Development of bioinformatic tools Diet analysis of endangered species Pollinator services
